Origin and history

The Dolmen de Roscasquen, also known as the dolmen de Kerpinvic, is a megalithic monument located in the commune of Quimperlé, in the Finistère department, Brittany. This simple dolmen, made of pink granite slabs, is distinguished by its monumental diamond-shaped cover table, measuring 4 metres long, 1.60 metres wide and 0.70 metres thick. The chamber, completely closed as a vault, could date from the Bronze Age according to certain assumptions, although its construction is attributed to the Neolithic.

The dolmen was searched and studied in the 19th century. It was reportedly explored by W.-C. Lukis in 1844, who drew up a plan. The monument is mentioned in several historical works, notably by Jean-Baptiste Ogée in 1852, Louis Flagelle in 1878, and Paul du Châtellier in 1907. These references attest to its importance in the study of Breton megaliths. Filed under the title of historic monuments by order of 3 April 1958, he enjoys heritage protection.

According to Pierre-Roland Giot, the dolmen could be a vault built at the Bronze Age, but built above ground due to the difficulty of digging the local basement. This hypothesis suggests an adaptation of funeral practices to geological constraints. The site is located precisely on the road from Pont-Scorff to Quimperlé, and its state of conservation, though partial, makes it a valuable testimony to the megalithic traditions of the region.

Available sources, including Wikipedia, Monumentum and archaeological inventories, highlight the scientific and historical interest of dolmen. Its classification among historic monuments reinforces its heritage value, while allowing its preservation for future generations. The dolmen of Roscasquen thus illustrates the richness of the Finistrian megalithic heritage, marked by various funeral buildings and architectural techniques adapted to the natural environment.
